Superdense stars containing strange baryons

This article is a review dedicated to the centenary of V. A. Ambartsumyan. The author, who is one of the first students of Ambartsumyan and G. S. Sahakyan in the area of superdense cosmology, presents the results of his first studies carried out jointly with Sahakyan, which were published immediately after the pioneering work of his teachers and supplemented their efforts. The results of studies by the author and various coauthors on superdense stars containing strange quarks are also discussed.
